Please let me know what you think about this PC build

Hi! So, the idea here is using this PC to stream 1080p, video edition (nothing crazy), and some regular games (not massive demanding games, but things like Half-Sword, some old shooters, and indie games). I have my PS5 if I want to play games that require high technical specifications. I also plan to use it to write a lot, and to record some music (guitar, drums, etc) but that's secondary, if anything.

My build:

CPU: AMD Ryzen 9 9900X 4.4 GHz 12-Core Processor
CPU Cooler: Thermalright Peerless Assassin 120 SE 66.17 CFM CPU Cooler
Motherboard: MSI B850 GAMING PLUS WIFI ATX AM5 Motherboard
Memory: Corsair Vengeance 32 GB (2 x 16 GB) DDR5-6000 CL30 Memory
Storage: Lexar NM790 2 TB M.2-2280 PCIe 4.0 X4 NVME Solid State Drive
Video Card: MSI VENTUS 2X OC GeForce RTX 5070 12 GB Video Card
Case: Montech AIR 903 BASE ATX Mid Tower Case
Power Supply: SeaSonic Focus GX V4 ATX 3 (2024) 750 W 80+ Gold Certified Fully Modular ATX Power Supply

And there you go. If you have any advice or recommendation, like signaling some "overkill" capabilities, or possible underperformance, or whatever, feel free to write bellow.

Thank you all!
